Member Function Documentation

◆ get_clone()

std::unique_ptr< SpanInterpolator > intrp::LinearSpanInterpolator::get_clone ( ) const
inlineoverridevirtual

Produce a std::unique_ptr that points to a copy of *this`.

Implements intrp::SpanInterpolator.

◆ interpolate()

double intrp::LinearSpanInterpolator::interpolate ( const gsl::span< const double > & source_points,
const gsl::span< const double > & values,
double target_point ) const
overridevirtual

Perform the interpolation of function represented by values at source_points to the requested target_point, returning the interpolation result.

Implements intrp::SpanInterpolator.

◆ required_number_of_points_before_and_after()

size_t intrp::LinearSpanInterpolator::required_number_of_points_before_and_after ( ) const
inlineoverridevirtual

The number of domain points that should be both before and after the requested target point for best interpolation. For instance, for a linear interpolator, this function would return 1 to request that the target is between the two domain points passed to source_points.

Implements intrp::SpanInterpolator.
